DETAILED DESCRIPTION

The following discussion and accompanying figures disclose a solestructure for an article of footwear. Concepts associated with thefootwear disclosed herein may be applied to a variety of athleticfootwear types, including soccer shoes, baseball shoes, football shoes,golf shoes, and hiking shoes and boots, for example. Accordingly, theconcepts disclosed herein apply to a wide variety of footwear types.

For consistency and convenience, directional adjectives are employedthroughout this detailed description corresponding to the illustratedembodiments. The term “longitudinal,” as used throughout this detaileddescription and in the claims, refers to a direction extending a lengthof a sole structure, i.e., extending from a forefoot portion to a heelportion of the sole. The term “forward” is used to refer to the generaldirection in which the toes of a foot point, and the term “rearward” isused to refer to the opposite direction, i.e., the direction in whichthe heel of the foot is facing.

The term “lateral direction,” as used throughout this detaileddescription and in the claims, refers to a side-to-side directionextending a width of a sole. In other words, the lateral direction mayextend between a medial side and a lateral side of an article offootwear, with the lateral side of the article of footwear being thesurface that faces away from the other foot, and the medial side beingthe surface that faces toward the other foot.

The term “horizontal,” as used throughout this detailed description andin the claims, refers to any direction substantially parallel with theground, including the longitudinal direction, the lateral direction, andall directions in between. Similarly, the term “side,” as used in thisspecification and in the claims, refers to any portion of a componentfacing generally in a lateral, medial, forward, and/or rearwarddirection, as opposed to an upward or downward direction.

The term “vertical,” as used throughout this detailed description and inthe claims, refers to a direction generally perpendicular to both thelateral and longitudinal directions. For example, in cases where a soleis planted flat on a ground surface, the vertical direction may extendfrom the ground surface upward. It will be understood that each of thesedirectional adjectives may be applied to individual components of asole. The term “upward” refers to the vertical direction heading awayfrom a ground surface, while the term “downward” refers to the verticaldirection heading towards the ground surface. Similarly, the terms“top,” “upper,” and other similar terms refer to the portion of anobject substantially furthest from the ground in a vertical direction,and the terms “bottom,” “lower,” and other similar terms refer to theportion of an object substantially closest to the ground in a verticaldirection.

For purposes of this disclosure, the foregoing directional terms, whenused in reference to an article of footwear, shall refer to the articleof footwear when sitting in an upright position, with the sole facinggroundward, that is, as it would be positioned when worn by a wearerstanding on a substantially level surface.

In addition, for purposes of this disclosure, the term “fixedlyattached” shall refer to two components joined in a manner such that thecomponents may not be readily separated (for example, without destroyingone or both of the components). Exemplary modalities of fixed attachmentmay include joining with permanent adhesive, rivets, stitches, nails,staples, welding or other thermal bonding, and/or other joiningtechniques. In addition, two components may be “fixedly attached” byvirtue of being integrally formed, for example, in a molding process.

Footwear Structure

FIG. 1 depicts an embodiment of an article of footwear 10, which mayinclude a sole structure 12 and an upper 14. For reference purposes,footwear 10 may be divided into three general regions: a forefoot region16, a midfoot region 18, and a heel region 20. Forefoot region 16generally includes portions of footwear 10 corresponding with the toesand the joints connecting the metatarsals with the phalanges. Midfootregion 18 generally includes portions of footwear 10 corresponding withan arch area of the foot. Heel region 20 generally corresponds with rearportions of the foot, including the calcaneus bone. Regions 16, 18, and20 are not intended to demarcate precise areas of footwear 10. Rather,regions 16, 18, and 20 are intended to represent general relative areasof footwear 10 to aid in the following discussion.

Since sole structure 12 and upper 14 both span substantially the entirelength of footwear 10, the terms forefoot region 16, midfoot region 18,and heel region 20 apply not only to footwear 10 in general, but also tosole structure 12 and upper 14, as well as the individual elements ofsole structure 12 and upper 14.

As shown in FIG. 1, upper 14 may include one or more material elements(for example, textiles, foam, leather, and synthetic leather), which maybe stitched, adhesively bonded, molded, or otherwise formed to define aninterior void configured to receive a foot. The material elements may beselected and arranged to selectively impart properties such asdurability, air-permeability, wear-resistance, flexibility, and comfort.An ankle opening 22 in heel region 20 provides access to the interiorvoid. In addition, upper 14 may include a lace 24, which may be utilizedto modify the dimensions of the interior void, thereby securing the footwithin the interior void and facilitating entry and removal of the footfrom the interior void. Lace 24 may extend through apertures in upper20, and a tongue portion 26 of upper 14 may extend between the interiorvoid and lace 24. Upper 14 may alternatively implement any of a varietyof other configurations, materials, and/or closure mechanisms. Forexample, upper 14 may include sock-like liners instead of a moretraditional tongue; alternative closure mechanisms, such as hook andloop fasteners (for example, straps), buckles, clasps, cinches, or anyother arrangement for securing a foot within the void defined by upper14.

Sole structure 12 may be fixedly attached to upper 14 (for example, withadhesive, stitching, welding, and/or other suitable techniques) and mayhave a configuration that extends between upper 14 and the ground. Solestructure 12 may include provisions for attenuating ground reactionforces (that is, cushioning the foot). In addition, sole structure 12may be configured to provide traction, impart stability, and/or limitvarious foot motions, such as pronation, supination, and/or othermotions.

The configuration of sole structure 12 may vary significantly accordingto one or more types of ground surfaces on which sole structure 12 maybe used, for example, natural turf (e.g., grass), synthetic turf, dirt,snow, synthetic rubber surfaces (e.g., running tracks) and other indoorsurfaces. In addition, the configuration of sole structure 12 may varysignificantly according to the type of activity for which footwear 10 isanticipated to be used (for example, running, hiking, soccer, baseball,football, and other activities).

Sole structure 12 may also vary based on the properties and conditionsof the surfaces on which footwear 10 is anticipated to be used. Forexample, sole structure 12 may vary depending on whether the surface isharder or softer. In addition, sole structure 12 may be tailored for usein wet or dry conditions.

In some embodiments, sole structure 12 may be configured for aparticularly specialized surface and/or condition. For example, in someembodiments, sole structure 12 may include a sole for a soccer shoeconfigured to provide traction and stability on soft, natural turfsurfaces in wet conditions. In some such embodiments, sole structure 12may include, for example, a low number of ground engaging members,wherein the ground engaging members are aggressively shaped, and havinga relatively large size. Conversely, an alternative embodiment of solestructure 12 may be configured to provide traction and stability onhard, artificial turf surfaces in dry conditions. In some suchembodiments, sole structure 12 may include, for example, a larger numberof ground engaging members, which may be relatively smaller in size, andmay have less aggressive shapes. While the number, size, and shape ofground engaging members are provided for exemplary purposes, otherstructural parameters may be varied in order to tailor the shoe fortraction and stability on various surfaces, and/or in a variety ofconditions. Additional such parameters may include, for example, the useof secondary traction elements, placement of ground engaging members,the relative softness or hardness of the ground engaging members and/orsole structure 12 in general, the relative flexibility of portions ofsole structure 12, and other such parameters.

In some embodiments, sole structure 12 may be configured forversatility. For example, sole structure 12 may be configured to providetraction and stability on a variety of surfaces, having a range ofproperties, and/or under various conditions. For example, a versatileembodiment of sole structure 12 may include a medium number of groundengaging members, having a medium size and moderately aggressive shapes.

In addition to surface properties and conditions, sole structure 12 mayalso be configured based on the physical characteristics of the athleteanticipated to wear the footwear, and/or according to the type ofactivity anticipated to be performed while wearing the footwear.Football players, depending on the position they play, can have a widerange of physical characteristics and abilities. For example, linemenmay be relatively heavy, relatively slower, but also much more powerfulthan players who play other positions. Linemen may place larger loads ona sole structure that may be sustained over longer durations, forexample, up to one or two seconds, while engaging with opposing linemen.

In contrast, skilled player positions, such as wide receivers, may berelatively lighter weight, but much faster. Skilled player positions,may place more explosive and transient loads on a sole structure, viasprinting, cutting, and jumping, and thus, may also maintain those loadsfor only a relatively short duration (for example, a split second).Linebackers may have physical characteristics and abilities thatrepresent a combination of the physical traits and abilities of linemenand wide receivers. While linebackers may possess speed and agility andoperate in open field like a wide receiver, linebackers may also belarger, heavier, and more powerful, and also engage other players intackling/blocking situations, like a lineman.

In view of the differing demands linemen and wide receivers may place onsole structures, sole structures most suitable for each type of playermay be configured differently. For example, the sole structures oflinemen shoes may be configured to be more stiff and durable, and alsoto distribute loads across the sole of the shoe. In contrast, widereceiver shoes may have sole structures that are configured for lightweight, more selective flexibility and stiffness at different areas ofthe foot, fast ground penetration and egress by ground engaging members,and lateral responsiveness. Further, a sole structure configured for useby a linebacker may be more versatile, possessing compromises ofstrength, stiffness, stability, light weight, directional traction, andother characteristics.

Other types of activities may place similar and/or different demands ona sole structure of a shoe. For example, soccer athletes may placesimilar demands as wide receivers, that is, loads based on speed andagility. Thus, soul structures having light weight, responsiveness, fastground penetration and egress, and traction in a variety of directionsand at a variety of ground contact angles may be advantageous. In othersports, the demands may be more focused. For example, sole structuresconfigured for use by track and field sprinters, who only run in astraight line at high speeds and accelerations, may be configured forlight weight, straight line traction, and fast surface penetration andegress. In contrast, a sole structure configured for hiking may beconfigured quite differently. For example, a hiking sole structure maybe configured to provide stability over uneven surfaces, protection fromharsh surfaces (such as sharp rocks), traction on uphill and downhillslopes, and grip on a variety of surfaces, for example, natural turf,dirt, rocks, wood, snow, ice, and other natural surfaces that may betraversed by a hiker.

The accompanying figures depict various embodiments of cleated shoes,having sole structures suited for natural and/or synthetic turf.Although footwear 10, as depicted, may be suited for soccer, such acleated shoe may be applicable for use in other activities on naturaland/or synthetic turf, such as baseball, football, and other suchactivities where traction and grip may be significantly enhanced bycleat members. In addition, various features of the disclosed solestructures (and/or variations of such features) may be implemented in avariety of other types of footwear.

In some embodiments, sole structure 12 may include multiple components,which may individually and/or collectively provide footwear 10 with anumber of attributes, such as support, rigidity, flexibility, stability,cushioning, comfort, reduced weight, and/or other attributes. In someembodiments, sole structure 12 may include an insole 26, a midsole 28, achassis 100, and a ground engaging sole component 30, as shown inFIG. 1. In some cases, however, one or more of these components may beomitted.

Insole 26 may be disposed in the void defined by upper 14. Insole 26 mayextend through each of regions 16, 18, and 20 and between the lateraland medial sides of footwear 10. Insole 26 may be formed of a deformable(for example, compressible) material, such as polyurethane foams, orother polymer foam materials. Accordingly, insole 26 may, by virtue ofits compressibility, provide cushioning, and may also conform to thefoot in order to provide comfort, support, and stability.

In some embodiments, insole 26 may be removable from footwear 10, forexample, for replacement or washing. In other embodiments, insole 26 maybe integrally formed with the footbed of upper 14. In other embodiments,insole 26 may be fixedly attached within footwear 10, for example, viapermanent adhesive, welding, stitching, and/or another suitabletechnique.

In some embodiments of footwear 10, upper 14 may surround insole 26,including on an underside thereof. In other embodiments, upper 14 maynot extend fully beneath insole 26, and thus, in such embodiments,insole 26 may rest atop midsole 28 (or atop chassis 100 in embodimentsthat do not include a midsole).

As noted above, footwear 10 is depicted in FIG. 1 as a soccer shoe.Although soccer shoes often do not include a midsole, since manyfeatures of footwear 10 may be applicable to shoes that do include amidsole (including soccer shoes as well as shoes for other activities),the general location of midsole 28 has been depicted in FIG. 1 as it maybe incorporated into any of a variety of types of footwear (includingsoccer shoes if they do include midsoles). Midsole 28 may be fixedlyattached to a lower area of upper 14 (for example, through stitching,adhesive bonding, thermal bonding (for example, welding), and/or othertechniques), or may be integral with upper 14. Midsole 28 may extendthrough each of regions 16, 18, and 20 and between the lateral andmedial sides of footwear 10. In some embodiments, portions of midsole 28may be exposed around the periphery of footwear 10. In otherembodiments, midsole 28 may be completely covered by other elements,such as material layers from upper 14. Midsole 28 may be formed from anysuitable material having the properties described above, according tothe activity for which footwear 10 is intended. In some embodiments,midsole 28 may include a foamed polymer material, such as polyurethane(PU), ethyl vinyl acetate (EVA), or any other suitable material thatoperates to attenuate ground reaction forces as sole structure 12contacts the ground during walking, running, or other ambulatoryactivities.

Ground Engaging Sole Component

An article of footwear according to the present disclosure may include asole structure including a ground engaging sole component fixedlyattached to the upper. The sole component may include features thatprovide traction and stability on any of a variety of surfaces, and inany of a variety of conditions.

The sole component may be formed by any suitable process. For example,in some embodiments, the sole component may be formed by molding. Inaddition, in some embodiments, various elements of the sole componentmay be formed separately and then joined in a subsequent process. Thosehaving ordinary skill in the art will recognize other suitable processesfor making the sole components discussed in this disclosure.

The sole component may include a baseplate and one or more groundengaging members extending downward from the baseplate. The baseplatemay include a substantially flat element that supports the foot, andserves as a substantially rigid platform from which the ground engagingmembers may extend.

FIG. 2 is a bottom perspective view of a first exemplary embodiment of aground engaging sole component 200 configured to be fixedly attached toan upper in order to form an article of footwear. FIG. 2 illustrates abottom surface 205 of sole component 200 viewed from a rear-medialposition.

Materials

The disclosed footwear components may be formed of any suitablematerials. In some embodiments, one or more materials disclosed in Lydenet al. (U.S. Pat. No. 5,709,954), which is hereby incorporated byreference in its entirety, may be used.

The components of the baseplate may be formed of any of a variety ofsuitable materials. In some embodiments the baseplate, the groundengaging members, and other elements of the sole component may beintegrally formed. For example, in some embodiments, the entirety of thesole component may be formed of a single material, forming all parts ofthe sole component. In such embodiments, the sole component may beformed all at once in a single molding process, for example, withinjection molding.

Different structural properties may be desired for different aspects ofthe sole component. Therefore, the structural configuration may bedetermined such that, even though a common material is used for allportions of the sole component, the different portions may be stiffer,or more flexible due to different shapes and sizes of the components.For example, the heel and midfoot regions of the baseplate may be formedof a thicker material and/or may include reinforcing features, such asribs, in order to provide stiffness to these portions of the solecomponent. Whereas, the forefoot region of the baseplate may be formedof a relatively thin material, in order to provide flexibility to theforefoot region. Greater flexibility in a forefoot region may enablenatural flexion of the foot during running or walking, and may alsoenable the sole component to conform to surface irregularities, whichmay provide additional traction and stability on such surfaces. Inaddition, the ground engaging members may be formed with a thickerstructure to provide rigidity and strength.

In other embodiments, different portions of the sole component may beformed of different materials. For example, a stiffer material, such ascarbon fiber, may be utilized in the heel and/or midfoot regions of thebaseplate, whereas a more flexible material, such as a thinpolyurethane, may be used to form the forefoot region of the baseplate.In addition, it may be desirable to utilize a stiffer and/or hardermaterial for the baseplate, such as carbon-fiber and/or polyurethane,and softer and more flexible material for the ground engaging members,such as a relatively hard rubber. Accordingly, in some embodiments, thesole component may be formed by multiple molding steps, for example,using a co-molding process. For instance, the baseplate may bepre-molded, and then inserted into a sole component mold, into which theground engaging member material may be injected to form the groundengaging members, or portions of the ground engaging members.

Sole component 200 may be formed of suitable materials for achieving thedesired performance attributes. Sole component may be formed of anysuitable polymer, composite, and/or metal alloy materials. Exemplarysuch materials may include thermoplastic and thermoset polyurethane(TPU), polyester, nylon, polyether block amide, alloys of polyurethaneand acrylonitrile butadiene styrene, carbon fiber, poly-paraphenyleneterephthalamide (para-aramid fibers, e.g., Kevlar®), titanium alloys,and/or aluminum alloys. In some embodiments, sole component 200 may beformed of a composite of two or more materials, such as carbon-fiber andpoly-paraphenylene terephthalamide. In some embodiments, these twomaterials may be disposed in different portions of sole component 200.Alternatively, or additionally, carbon fibers and poly-paraphenyleneterephthalamide fibers may be woven together in the same fabric, whichmay be laminated to form sole component 200. Other suitable materialsand composites will be recognized by those having skill in the art.

Baseplate

As shown in FIG. 2, sole component 200 may include a baseplate 202.Baseplate 202 may be a substantially flat, plate-like platform.Baseplate 202, although relatively flat, may include various anatomicalcontours, such as a relatively rounded longitudinal profile, a heelportion that is higher than the forefoot portion, a higher arch supportregion, and other anatomical features. In addition, baseplate 202 mayinclude a bottom surface 205, which may be generally flat, but may havevarious contours that provide stiffness, strength, and/or traction.

Ground Engaging Members

Sole component 200 may include one or more ground engaging members 210to provide traction and/or stability. It will be understood that avariety of types of ground engaging members could be implemented by solecomponent 200. Sole component 200 may include ground engaging membershaving any of a variety of shapes, sizes, and arrangements based on anumber of factors. The configuration of ground engaging members utilizedfor sole component 200 may be based on the considerations discussedabove, for example, the physical attributes of the player, the nature ofthe surface on which the activity is performed, and the conditions ofthat surface.

In some cases, ground engaging members 210 could be configured to engagea soft ground surface. For example, in one embodiment, ground engagingmembers 210 could be configured to engage a soft grass surface. In othercases, ground engaging members 210 could be configured to engage a hardsurface. For example, in one embodiment ground engaging members 210could be configured to engage a hard grass surface or artificial turf.In still other embodiments, other types of ground engaging members couldbe used.

The ground engaging members may be configured to provide traction andstability on any of a variety of surfaces, and in under any of a varietyof surface conditions. As depicted in FIG. 2, sole component 200equipped with ground engaging members 210 is a versatile sole structure,which may be suitable for a variety of surfaces. For example, the groundengaging members shown in the accompanying figures may be suited for avariety of relatively soft surfaces, such as natural or cushionedsynthetic turf, relatively soft-packed dirt, and other compliantsurfaces. However, the features shown and discussed in the presentdisclosure may also be applicable for relatively hard surfaces wherecleated shoes may be utilized. Exemplary such surfaces may include, forexample, relatively un-cushioned synthetic turf, hard-packed dirt orcinders, such as may be found on a baseball field or a running track, orsynthetic rubber, such as may be found on other types of running tracks.

Further, while sole component 200 could be configured for any of varioustypes of users, surfaces, and/or conditions, sole component 200 (andother presently disclosed sole component embodiments), as depicted inFIG. 2, is configured for speed and agility, and may be suitable forlighter weight athletes demonstrating, or looking to improve, speed andquickness. Sole component 200 shown in FIG. 2 (and other presentlydisclosed sole component embodiments) is depicted as a sole for a soccershoe. However, such a sole configuration, either as shown or with minormodifications, could be utilized for other activities, such as baseball,football, and/or other activities.

Exemplary disclosed ground engaging members may have one or morefeatures that facilitate ground penetration and/or ground extraction.Such features may include, for example, shapes, sizes, positioning onthe sole component, as well as the orientation of the ground engagingmembers. For example, in some embodiments, the ground engaging membersmay have an elongate cross-sectional horizontal shape. Further, theelongate shape may be narrower at one end or the other. Such a narrowerend may facilitate ground penetration in the way a pointed implement isconfigured for ground penetration. In addition, a narrower end may alsofacilitate ground extraction (that is, the removal of the groundengaging member from the ground after penetration).

As shown in FIG. 2, in some embodiments, ground engaging members 210 mayhave a horizontal cross-sectional shape that is substantially elongate.For example, as shown in cross sectional view 215 in FIG. 2, groundengaging members 210 may have a cross-sectional shape similar to anairfoil. In some embodiments, an airfoil shape may be formed by virtueof having a slight curvature, as shown in the figures, as well asdiffering widths at the front and rear of the ground engaging member.For example, as shown in cross-sectional view 215 in FIG. 2, groundengaging members 210 may have a forward width 235 and a rearward width240, wherein forward width 235 is narrower than rearward width 240.

In some embodiments, forward width 235 may be approximately 0.5-4.0 mm,whereas rearward width 240 may be approximately 3.0-8.0 mm. Thesedimensions may vary depending upon the portion of sole component 200 onwhich the ground engaging member is disposed. For example, in someembodiments, a forefoot ground engaging member may have a forward width235 that is approximately 2.0 mm, and a rearward width 240 that isapproximately 5.0 mm. In contrast, in some embodiments, a heel groundengaging member may have a forward width 235 that is approximately 4.0mm, and a rearward width 240 that is approximately 6.5 mm.

Exemplary elongate ground engaging members 210 may have a length 245that is substantially longer than either forward width 235 or rearwardwidth 240. For example, in some embodiments, length 245 may be in therange of approximately 10.0-30.0 mm (1-3 cm). For example, in someembodiments, forefoot ground engaging members may have a length 245 ofapproximately 16 mm. This exemplary length 245 is at least three timeslarger than the width of any portion of the exemplary forefoot groundengaging member dimensions mentioned above. Also, in some embodiments,heel ground engaging members may have a length 245 of approximately 20mm. This exemplary length 245 is also at least three times larger thanthe width of any portion of the exemplary heel ground engaging membermentioned above.

Other elongate shapes are also possible, such as oval, rectangular,racetrack, and others. For example, FIGS. 3A and 3B show an alternativeelongate ground engaging member embodiment. FIGS. 3A and 3B show aground engaging sole component 300, including a baseplate 302 having abottom surface 305, and a substantially curved ground engaging member310. The radius of curvature of ground engaging member 310 may besubstantially smaller than the radius of curvature of airfoil-shapedground engaging members 210. That is, ground engaging member 310 may bemore tightly curved than ground engaging member 210, as shown. However,any suitable curvature may be used for ground engaging members.

Exemplary ground engaging members may also include features that provideadditional traction in a region of the foot. For example, additionaltraction may be desired in a region of a shoe corresponding with thefirst distal phalanx of the foot. In some embodiments, a ground engagingmember may be utilized in this region that has a substantially longerlength. In such embodiments, a ground engaging member may include dualdownward projections. By splitting the lengthened ground engaging memberinto dual projections, ground penetration may be improved over a singlelong projection. In addition, dual projections may be utilized to affectweight distribution among ground engaging members.

Referring again to FIGS. 3A and 3B, ground engaging member 310 mayinclude dual projections 315 with a bridge 320 between dual projections315. A ground engaging member having the configuration of groundengaging member 310 may be incorporated at any suitable location on aground engaging sole component.

In some embodiments, the cross-sectional shape of ground engagingmembers 210 may be substantially irregular. For example, FIGS. 4A and 4Bshow an alternative ground engaging member embodiment. FIGS. 4A and 4Bshow a ground engaging sole component 400, including a baseplate 402having a bottom surface 405, and a ground engaging member 410 having atilde-shaped horizontal cross-sectional shape.

Some embodiments may include ground engaging members having featuresthat facilitate weight reduction of the ground engaging sole component.For example, some ground engaging members may have holes passing throughthe ground engaging member, thus eliminating extra material withoutsubstantially reducing strength or rigidity. For Example, referringagain to FIGS. 4A and 4B, in some embodiments, ground engaging members410 may include holes 415 passing through ground engaging members 410.Ground engaging members having weight-reducing holes may be utilized inany suitable locations on a sole component. Exemplary such locations mayinclude places where larger ground engaging members are disposed. Forexample, heel regions often have longer cleats in order to accommodate araised heel region of the sole component as discussed above. See, forexample, FIG. 20. In addition, regions where ground engaging membershave been grouped closely, or where a dual projection ground engagingmember, such as ground engaging member 310 shown in FIGS. 3A and 3B, mayutilize holes in the ground engaging members to reduce the amount ofweight clustered in that region of the shoe. See FIG. 19.

Ground engaging members may also have a substantially regularcross-sectional shape. For example, in some embodiments, ground engagingmembers may have a circular cross-sectional shape. Circular groundengaging members may be less costly to produce, and may also providerelatively even traction in all horizontal directions. Circular roundengaging members may also provide traction, while still allowingrotation of a foot about the circular ground engaging member while incontact with the ground. This may facilitate pivoting on a planted foot,which may, in turn, enable rapid changes in direction by the athlete,and promote freedom of motion.

FIG. 5 illustrates an alternative ground engaging member embodiment. Forexample, FIG. 5 shows a ground engaging sole component 500, which mayinclude a baseplate 502 having a bottom surface 505, and a groundengaging member 510 having a substantially round cross-sectional shape.In some embodiments, ground engaging member 510 may be substantiallyconical, as shown in FIG. 5. Substantially round ground engaging membersmay be utilized at any suitable location of a sole component. In someembodiments, round ground engaging members may be disposed at a regionof the sole component corresponding with the first metatarsal headregion of the wearer's foot and/or at the region of the footcorresponding with a distal portion of the first phalanx. See, forexample, FIG. 19. An athlete may place a significant amount of theirweight on these regions of their foot when pivoting. Therefore,placement of round ground engaging members at these locations mayfacilitate pivoting, while still maintaining traction.

Support Members

In addition to ground engaging members, a ground engaging sole componentmay include one or more features to provide reinforcement to the groundengaging members, increase traction, and facilitate ground penetrationand extraction. In some embodiments the ground engaging sole componentmay include one or more elongate support members extending downward fromthe bottom surface of the baseplate of the sole component, abutting theside portions of the ground engaging members, and extending horizontallyfrom the ground engaging members. Examples of such elongate supportmembers are disclosed in co-pending U.S. application Ser. No.13/009,549, filed Jan. 19, 2011, entitled “Composite Sole Structure,”the disclosure of which is hereby incorporated by reference in itsentirety; and co-pending U.S. application Ser. No. 12/582,252, filedOct. 20, 2009, entitled “Article of Footwear with Flexible ReinforcingPlate,” the disclosure of which is hereby incorporated by reference inits entirety.

By spanning between ground engaging members and the bottom surface ofthe baseplate, elongate support members may buttress, brace, orotherwise reinforce the ground engaging members. This may providereinforcement, such as, for example, increased stiffness and/or strengthto the ground engaging members.

The amount of reinforcement provided by the elongate support members maybe dependent on the shape, size (length, height, thickness), material,placement, and or orientation of the support members. The amount ofreinforcement provided may also depend on the number of support membersused on each ground engaging member. The foregoing parameters may bevaried to achieve the desired level of reinforcement for a given groundengaging member. In some cases, weight may be reduced by using athinner, lighter weight ground engaging member, while the strength andstiffness of the ground engaging member may be maintained by theinclusion of one or more elongate support members, which may provide thesame amount of strength and stiffness using less material.

Similarly, the reduction of material from the ground engaging membersmay increase ground penetration. For example, when elongate supportmembers are used, the cross-section of the ground engaging members maybe reduced, allowing for increased ground penetration. The addition ofthe support members provides little, if any, additional impedance toground penetration because the support members are relatively thin, andthus readily penetrate the ground. In addition, the support members maybe configured such that they do not extend the full length of the groundengaging members, thus, a significant portion of the ground engagingmembers may penetrate the ground before the support members even engagethe ground. Also, the support members may have a sloped configuration,which may also facilitate ground penetration of the support membersthemselves.

In addition to reinforcement and ground penetration, the elongatesupport members may provide increased traction. As additional elementsthat extend from the bottom surface of the sole component baseplate, thesupport members may serve as secondary traction elements. In addition,because the support members may be elongate, the traction provided, likethe reinforcement, is substantially directional. That is, an elongatesupport member provides the most traction in a direction perpendicularto the direction in which it is elongated. Thus, the orientation of eachelongate support member may be selected to provide traction in a desireddirection at a desired region of the ground engaging sole component.Accordingly, additional traction may be provided specifically in alongitudinal (forward-rearward) direction or a lateral (lateral-medial)direction, or at any angle between longitudinal and lateral. It is notedthat the direction in which an elongate support member provides the mostreinforcement is perpendicular to the direction in which it provides themost traction. This factor may be considered when selecting supportmember configurations.

By extending one or more elongate support members substantially radially(or at other angles) from a ground engaging member, torsional tractionmay be provided about the ground engaging member. Torsional traction isa characteristic that may be either desirable or undesirable dependingon the application. For example, for certain activities, it may bebeneficial to have greater freedom of motion. Accordingly, for suchactivities, a reduced size and/or number of support members may beutilized at regions of the foot that may serve as pivot points duringthe activity. For other activities, it may be desirable to provideincreased torsional traction in order to increase performance. Forexample, it may be advantageous to provide a golf shoe with increasedtorsional traction at certain portions of the foot, in order to enable agolfer to generate more torque by twisting his body during a swing.

In some cases, it may be advantageous on one foot to provide increasedtorsional traction, and on the other foot to provide decreased torsionaltraction. For example, while a golfer may want additional torsionaltraction at one or more portions of his rear foot (away from the hole)to enable him to execute a more powerful swing, he may want a reducedamount of torsional traction at one or more portions on his front foot(closer to the hole), to enable greater freedom of motion. Depending onthe portion of the foot in question, the opposite may also be true. Thatis, it may be desirable to provide one or more portions of the rear footwith a reduced amount of torsional traction and provide one or moreportions of the front foot with an increased amount of torsionaltraction.

Torsional traction systems may be advantageous for any type of activitywhere it would be beneficial to generate torque with the body. Forexample, increased agility may be provided by enabling increased torqueto be generated when changing directions. In addition, other exemplarysuch activities may involve asymmetric motions, such as throwing,swinging, kicking, and other motions. Therefore, exemplary applicationswhere torsional traction systems could be implemented may include, forexample, golf (as noted above), baseball (both hitting and throwing),javelin, soccer (both kicking).

The foregoing outlines a multitude of parameters regarding thestructural configuration of support members that may be manipulated toprovide desired reinforcement, ground penetration, and tractioncharacteristics at specific locations of the sole of an article offootwear. Accordingly, the shape, size, material, placement,orientation, and other specifications of each individual support membermay be chosen to achieve the desired performance characteristics. Thiscustomization of multiple components of a cleat system is reflected inthe asymmetric and irregular support member configurations in thedisclosed embodiments. It is noted that, as illustrated in theaccompanying figures and described in greater detail below, the shape,size, orientation, and other parameters of support members may beinconsistent among ground engaging members in the same sole structureembodiment. Further, it should also be noted that, such variation mayalso exist among support members about a common ground engaging member.

In addition, the configuration of support members may also be variedaccording to the size of the article of footwear. For example, largersizes of footwear may use a similar arrangement of ground engagingmembers. However, for larger shoe sizes (e.g., box sizes), the spacingbetween the ground engaging members may be significantly greater. Acrossa size range, the spacing between a forefoot ground engaging member anda heel ground engaging member may vary by several centimeters. In orderto provide additional traction in the larger spaces between groundengaging members for larger shoe sizes, longer support members and/orsupport members having an alternative shape may be utilized between theground engaging members. Similarly, it may be advantageous to alter theconfiguration of support members by selectively reducing the size of thesupport members in certain areas. For example, in some embodiments,smaller sizes may include support members that effectively bridge theentire gap between ground engaging members by spanning between themembers. However, for larger sizes, the distance between two groundengaging members may be much larger such that a support member thatextends the full gap between the ground engaging members may provide alevel of traction that exceeds the desired amount. In such cases, it maybe beneficial to omit the central portion of the bridging support memberfor larger size footwear.

Shape of Support Members

The shape of support members may provide reinforcement, groundpenetration, and traction. The elongate configuration of support membersis discussed above as providing directional reinforcement, directionaltraction, and ground penetration and extraction. In addition, in someembodiments, other aspects of the support member shape may influencethese characteristics.

FIG. 6A illustrates an exemplary support member configuration. Asillustrated in FIG. 6A, a ground engaging sole component 600 may includea baseplate 602 having a bottom surface 605, and a ground engagingmember 610 extending downward from bottom surface 605. Sole component600 may also include one or more elongate support members 630 extendingsubstantially downward from bottom surface 605 of baseplate 602,abutting ground engaging member 610 at side portions thereof, andextending horizontally from the side portions of ground engaging member610.

In some embodiments, one or more of elongate support members 630 mayinclude a downward facing surface 635 that is substantially planar. Itmay be more cost effective to produce support members with planardownward facing surfaces, as the molds may be simpler to make. Inaddition, the mechanical properties of support members having planardownward facing surfaces may also be simpler to calculate, which mayfacilitate the process of developing a tread system with the desiredproperties. Further, edges 660 between downward facing surfaces 635 andvertical surfaces 640 of support members 630 may provide additionaltraction over and above alternative shapes, such as rounded downwardfacing surfaces.

In some embodiments, support members may have downward facing surfacesthat are sloped, for example, extending at angles between the groundengaging members to the bottom surface of the baseplate at locationsthat are relatively near, but spaced from, the ground engaging member.These angles may be varied from support member to support member and/orfrom ground engaging member to ground engaging member. Further, in someembodiments, a single ground engaging member may have a faceted downwardfacing surface, wherein each facet is oriented at a different slopeangle.

Different slope angles may provide different levels of reinforcement byvirtue of having the support provided at differing angles, as well as byinfluencing the size of the support member. In addition, slope anglesmay also affect ground penetration, with steeper angles providing betterground penetration. In some embodiments, faceted downward facingsurfaces may have their steepest portions (closest to vertical) nearestthe ground engaging member to which it is abutted. These portions thatare closest to the ground engaging members are furthest from the bottomsurface of the baseplate and, therefore, are the portions of the supportmembers that extend the furthest downward. Accordingly, as the solecomponent comes into contact with the ground, these portions engage theground before (and therefore in more circumstances than) the portions ofthe support members that are disposed further away from the groundengaging members. In addition, the dual angles of a support member mayenable the traction provided by the support members to be focused in theareas immediately surrounding the ground engaging members, while stillproviding additional reinforcement due to the wider extension of theportions of the support members closer to the baseplate in directionshorizontally away from the ground engaging members.

It should be noted that the isolated depictions of first elongatesupport member 645, second elongate support member 650, and thirdelongate support member 655 in FIG. 6A are schematic and are providedfor dimensional illustration. While these components could beimplemented having shapes substantially as shown (with profiles of righttriangles), in some embodiments, the side portions that abut the groundengaging member may have some degree of curvature in conformity with theshape of the ground engaging member, which can flare at a top portionwhere it abuts the bottom surface of the baseplate.

In some embodiments, downward facing surfaces 635 may extend at slopeangles from the side portions of ground engaging members 630 to bottomsurface 605 of baseplate 602 proximate to ground engaging members 630.In some embodiments, downward facing surfaces 635 of elongate supportmembers 630 may have slope angles that differ from one another. Forexample, sole component 600 may include a first elongate support member645, a second elongate support member 650, and a third elongate supportmember 655. As shown in FIG. 6A, first elongate support member 645,second elongate support member 650, and third elongate support member655 may each have a different shape and/or size and, accordingly, mayhave downward facing surfaces extending at different slope angles. Forexample, elongate support member 645 may have a first height H1, a firstlength L1, and a first slope angle α1 measured with respect tohorizontal. In addition, second elongate support member 650 may have asecond height H2, a second length L2, and a second slope angle α2.Further, third elongate support member 655 may have a third height H3, athird length L3, and a third slope angle α3. Exemplary approximatedimensions for the foregoing components are provided in the table shownin FIG. 6B.

FIG. 7 illustrates an alternative exemplary support memberconfiguration. As shown in FIG. 7, a ground engaging sole component 700may include a baseplate 702 having a bottom surface 705, and a groundengaging member 710 extending downward from bottom surface 705. Solecomponent 700 may also include one or more elongate support members 730extending substantially downward from bottom surface 705 of baseplate702, abutting ground engaging member 710 at side portions thereof, andextending horizontally from the side portions of ground engaging member710. A peaked downward facing surface may facilitate ground penetrationof a support member.

In some embodiments, sole component 700 may include a peaked elongatesupport member 735. As shown in FIG. 7, peaked elongate support member735 may have a downward facing surface 740 at least a portion of whichis substantially peaked. That is peaked elongate support member 735 mayhave a downward ridge 740 at which opposing faces of downward facingsurface 745 may intersect.

FIG. 8 illustrates an alternative support member configuration. FIG. 8shows a ground engaging sole component 800, which may include abaseplate 802 having a bottom surface 805, and a ground engaging member810 extending downward from bottom surface 805. Sole component 800 mayalso include one or more elongate support members 830 extendingsubstantially downward from bottom surface 805 of baseplate 802,abutting ground engaging member 810 at side portions thereof, andextending horizontally from the side portions of ground engaging member810.

In some embodiments, one or more of elongate support members 830 mayinclude a downward facing surface that is faceted. As shown in FIG. 8,the downward facing surface may be faceted, such that each facet extendsat a different slope angle. For example, sole component 800 may includea first elongate support member 835 and a second elongate support member840. First elongate support member 835 may have a downward facingsurface 845.

In some embodiments, downward facing surface 845 may be faceted.Downward facing surface 845 may include a first facet 850 and a secondfacet 855. In some embodiments, first facet 850 and second facet 855 maybe substantially planar. As shown in FIG. 8, first facet 850 and secondfacet 855 may be angled at different non-horizontal orientations. Thatis, first facet 850 and second facet 855 may extend at different slopeangles. For example, first facet 850 may extend horizontally and upwardfrom ground engaging member 810 at a first slope angle 860, and secondfacet 855 may extend horizontally and upward at a second slope angle865.

In some embodiments, slope angles 860 and 865 may be different. Further,in some embodiments, slope angles 860 and 865 may both extend atdifferent non-horizontal orientations, as shown in FIG. 8. In someembodiments, wherein first facet 850 is disposed adjacent groundengaging member 810 and between ground engaging member 810 and secondfacet 855, first slope angle 860 may be steeper (closer to vertical)than second slope angle and 865, as shown in FIG. 8.

The advantages of having support members that are elongate are discussedin detail above. The degree to which a support member is elongate isrelated to the thickness or horizontal width of the support member. Thisthickness may vary from support member to support member and/or fromground engaging member to ground engaging member. Further, the thicknessof each support member may be consistent along its length or may vary.For example, in some embodiments, the thickness may taper with distancefrom the ground engaging member to which the support member abuts.

Referring again to FIG. 4A, in some embodiments, the elongate supportmember may taper with distance from the ground engaging member. Forexample, sole component 400 may include one or more elongate supportmembers 430. A first elongate support member 435 may include ahorizontal length 440. In addition, first elongate support member 435may have a first horizontal width 445 (thickness) at an end proximal toground engaging member 410, and a second horizontal width 450 furtheraway from ground engaging member 410. In some embodiments, secondhorizontal width 450 may be narrower than first horizontal width 445,and thus, may taper with distance from ground engaging member 410.

Tapering support members may provide benefits in ground penetration andextraction. As a ground engaging member penetrates the ground, the forcerequired to create further penetration may increase. The added forcerequired may be greater still if additional parts of the sole component(such as support members) come into contact with the ground as primaryground engaging members penetrate. In some cases, it may be desirable tofacilitate deeper ground penetration, while maintaining the benefits ofsupport members. In such cases, it may be advantageous to providesupport members with tapered profiles, in order to better enable groundpenetration of the uppermost portions of the support members.

Referring again to FIG. 5, sole component 500 may include one or moreelongate support members 530. A first elongate support member 535 mayhave a horizontal length 540 and a horizontal width 545 (thickness). Insome embodiments, horizontal width 545 may be substantially the sameover the entire horizontal length 540 of first elongate support member535.

It may be beneficial to form support members with a consistenthorizontal width in order to simplify manufacturing. A consistentthickness may also provide consistent traction and ground penetrationrelated to the thickness, allowing traction and ground penetration to bedetermined by other factors, such as slope angle, orientation, and sizeof the support member.

Some embodiments may include an elongate support member that has alowermost surface that extends, over a first distance, substantiallyhorizontally away from the ground engaging member to which it abuts. Insome such embodiments, the support member may project further downwardover a second distance to form a second ground engaging member.

Referring again to FIG. 7, sole component 700 may include a secondelongate support member 750. Second elongate support member 750 mayinclude a lowermost surface 755. As shown in FIG. 7, second elongatesupport member 750 may include a first portion 760 wherein lowermostsurface 755 extends substantially horizontally away from ground engagingmember 710. In addition, second elongate support member 750 may includea second portion 765 wherein lowermost surface 755 projects furtherdownward to form a second ground engaging member 770.

By providing a second ground engaging member depending from a supportmember, ground engaging members may be clustered in a particular area ofthe sole component. In addition, both the first and second groundengaging members may benefit from the reinforcement provided by thesupport member.

In some embodiments, one or more of the elongate support members mayhave a curvature as it extends horizontally from the ground engagingmember to which it abuts. As shown in FIG. 7, peaked elongate supportmember 735 extends horizontally from ground engaging member 710 in adirection having a curvature. Peaked elongate support member 735 mayhave a first radius of curvature 775. In addition, ground engagingmember 710 may have a second radius of curvature 780. As shown in FIG.7, the curvature of peaked elongate support member 735 may differ fromthe curvature of ground engaging member 710. In addition, in someembodiments, the curvature of peaked elongate support member 735 and thecurvature of the ground engaging member 710 may be reversed, as alsodepicted in FIG. 7. Curved ground engaging members and/or curvedelongate support members may be applicable for use in any suitablelocation. For example, such curved components may be suitable for use inregions of the foot that are curved, such as at the junction between thearch of the foot and the first metatarsal head.

Orientation of Support Members

While the amount of reinforcement, ground penetration, and/or tractionmay be controlled by varying the shape of the support members, asdiscussed above, the direction in which the reinforcement and tractionmay be provided may also be controlled. Each elongate support member mayprovide reinforcement and traction in multiple directions. However, dueto the elongate structure, each elongate support member may provide themost reinforcement in the direction of its elongation. For example, anelongate support member that extends medially from a ground engagingmember may provide the greatest reinforcement in the lateral and medialdirections. Such a support member may, additionally, providereinforcement in forward and rearward directions, albeit to a lesserdegree. Thus, the direction of reinforcement provided by the elongatesupport members may be controlled by selecting the orientation of thesupport member. Similarly, the direction of greatest traction providedby support members may be substantially perpendicular to the directionof elongation.

In some embodiments, one or more support members may extendsubstantially radially from an approximate center portion of a groundengaging member. In some embodiments, one or more support members mayextend in a substantially non-radial direction. In some embodiments, allsupport members abutting the same ground engaging member may extendradially from the ground engaging member. In some embodiments, allsupport members abutting the same ground engaging member may extend in asubstantially non-radial direction. Further, in some embodiments, bothradially and non-radially oriented support members may abut the sameground engaging member.

FIG. 9 is a bottom view of a portion of a ground engaging sole component900. Sole component 900 may include a baseplate 902 having a bottomsurface 905. Sole component 900 may also include a ground engagingmember 910. As shown in FIG. 9, ground engaging member 910 may have asubstantially elongate horizontal cross-sectional shape. Sole component900 may further include one or more elongate support members 930. Forexample, as shown in FIG. 9, sole component 900 may include a firstelongate support member 935, a second elongate support member 940, and athird elongate support member 945. As shown in FIG. 9, first elongatesupport member 935 and second elongate support member 940 may extendsubstantially radially from an approximate center portion 950 of groundengaging member 910.

Center portion 950 is intended to reflect an approximation of the centerof ground engaging member 910. In some embodiments, the approximatecenter portion may relate to the geometric center (centroid) of theground engaging member. In other embodiments, the center portion maysimply be the intersection of lines bisecting the length and width ofthe ground engaging member. As noted above, however, the center portionis not necessarily intended to be a precise center point according toany particular convention, although it could be in some embodiments.Rather, the center portion is intended to be approximate and is utilizedin this description to differentiate between support members that areoriented substantially radially and support members that have asubstantially non-radial orientation.

As shown in FIG. 9, first elongate support member 935 may extend along afirst radial axis 955. Second elongate support member 940 may extendalong a second radial axis 960. First radial axis 955 and second radialaxis 960 may intersect center portion 950. Third elongate support member945 may extend along a substantially non-radial axis 965. As shown inFIG. 9, non-radial axis 965 does not intersect with center portion 950.The use of radial and/or non-radial support members may be based onconsiderations discussed above regarding reinforcement, groundpenetration and extraction, and traction, including the directionalityof each of these properties.

In some embodiments, all support members abutting the same groundengaging member may be radially oriented. In addition, both radial andnon-radial support members may abut ground engaging members having anyhorizontal cross-sectional shape. FIG. 10 illustrates an alternativesupport member configuration. FIG. 10 is a bottom view of a portion of aground engaging sole component 1000. Sole component 1000 may include abaseplate 1002 having a bottom surface 1005. Sole component 1000 mayalso include a ground engaging member 1010. As shown in FIG. 10, groundengaging member 1010 may have a substantially round (circular)cross-sectional shape.

Sole component 1000 may further include one or more elongate supportmembers 1030. For example, as shown in FIG. 10, sole component 1000 mayinclude a first elongate support member 1035, a second elongate supportmember 1040, and a third elongate support member 1045. As shown in FIG.10, first elongate support member 1035, second elongate support member1040, and third elongate support member 1045 may all extendsubstantially radially from an approximate center portion 1050 of groundengaging member 1010. For example, as shown in FIG. 10, first elongatesupport member 1035 may extend along a first radial axis 1055. Inaddition, second elongate support member 1040 may extend along a secondradial axis 1060, and third elongate support member 1045 may extendalong a third radial axis 1065. First radial axis 1055, second radialaxis 1060, and third radial axis 1065 may all intersect center portion1050.

In some embodiments, wherein the ground engaging member is elongate,support members may be selectively oriented to be either in substantialalignment or substantial non-alignment with the direction in which theground engaging member is elongated. The alignment of support memberswith elongate ground engaging members may vary from support member tosupport member and/or from ground engaging member to ground engagingmember. For example, in some embodiments support members may beconsistently aligned or non-aligned about a common ground engagingmember to which all the support members are abutted. In someembodiments, support members may be consistently aligned or non-alignedthroughout an arrangement of ground engaging members. In otherembodiments, both aligned and non-aligned support members may beimplemented in the same arrangement of ground engaging members and/oreven about the same ground engaging member.

FIG. 11 illustrates another exemplary support member configuration. FIG.11 is a bottom view of a portion of a ground engaging sole component1100. Sole component 1100 may include a baseplate 1102 having a bottomsurface 1105. Sole component 1100 may also include a ground engagingmember 1110. As shown in FIG. 11, ground engaging member 1110 may have asubstantially elongate cross-sectional shape.

Sole component 1100 may further include one or more elongate supportmembers 1130. For example, as shown in FIG. 11, sole component 1100 mayinclude a first elongate support member 1135, a second elongate supportmember 1140, and a third elongate support member 1145. As shown in FIG.11, third elongate support member 1145, and at least one of firstelongate support member 1135 and second elongate support member 1140 maybe independent of any other ground engaging members extending frombaseplate 1102.

As used in this detailed description and in the claims, the term“independent,” shall refer to a lack of interaction and/or connection ofan elongate support member with a ground engaging member other than theground engaging member to which it abuts. Further, the term“independent” shall also refer to the lack of interaction and/orconnection of an elongate support member with any other support membersabutting another ground engaging member.

Ground engaging member 1110 may be elongated along a ground engagingmember axis 1155. As shown in FIG. 11, first elongate support member1135 and second elongate support member 1140 may each extend along anaxis that is substantially aligned with ground engaging member axis1155. In addition, third elongate support member 1145 may extend along asecond support member axis 1160. As shown in FIG. 11, second supportmember axis 1160, and thus second elongate support member 1140, may beoriented in non-alignment with ground engaging member axis 1155.Further, in some embodiments, second elongate support member 1140 may beoriented substantially perpendicular to ground engaging member axis1155. As shown in FIG. 11, second elongate support member 1140 may bedisposed at a first angle 1165 with respect to ground engaging memberaxis 1155. In some embodiments, first angle 1165 may be approximately 90degrees. First angle 1165 represents the angle between second elongatesupport member 1140 and third elongate support member 1145. In addition,a second angle 1170 represents the angle between first elongate supportmember 1135 and third elongate support member 1145. Thus, in embodimentswhere third elongate support member 1145 is disposed substantiallyperpendicular to ground engaging member axis 1155, second angle 1170 maybe approximately 90 degrees.

Alternative embodiments, wherein an elongate support member extends in adirection that is in substantial non-alignment with an elongate groundengaging member, are depicted FIGS. 3A, 3B, and 7, which are discussedabove. As shown in FIGS. 3A and 3B, sole component 300 may include anelongate support member 330 extending from ground engaging member 310.Support member 330 may abut ground engaging member 310 between dualprojections 315 of ground engaging member 310. See also elongate supportmember 730 in FIG. 7, which may be oriented similarly with respect todual projections 715 of ground engaging member 710.

Referring again to FIG. 11, first elongate support member 1140 andsecond elongate support member 1145 may be disposed on opposite sides ofground engaging member 1110, in substantial alignment with groundengaging member axis 1155. Therefore, first elongate support member 1140and second elongate support member 1145 may be disposed in substantialalignment with each other. Accordingly, in such embodiments, third angle1175 may be approximately 180 degrees.

In some embodiments, support members on opposite sides of a groundengaging member may be substantially parallel to each other withoutbeing in alignment with each other. FIG. 12 is a bottom view of aportion of a ground engaging sole component 1200. Sole component 1200may include a baseplate 1202 having a bottom surface 1205. Solecomponent 1200 may also include a ground engaging member 1210. As shownin FIG. 12, ground engaging member 1210 may have a substantiallyelongate cross-sectional shape.

Sole component 1200 may further include one or more elongate supportmembers 1230. For example, as shown in FIG. 12, sole component 1200 mayinclude a first elongate support member 1235, a second elongate supportmember 1240, and a third elongate support member 1245. First elongatesupport member 1235 and second elongate support member 1240 may bedisposed substantially on opposite sides of ground engaging member 1210.First elongate support member 1235 may extend along a first axis 1255and second elongate support member 1240 may extend along a second axis1260. In some embodiments, first axis 1255 and second axis 1260 may besubstantially parallel with one another but not aligned with oneanother, as shown in FIG. 12. For example, as shown in FIG. 12, firstaxis 1255 and second axis 1260 may be separated by a distance 1265. Insome embodiments, third elongate support member 1245 may be omitted.

Spacing of Support Members

For many of the same reasons it may be desirable to have spacing betweenground engaging members that is chosen to achieve certain performanceparameters, it may also be desirable to select spacing between supportmembers about a common ground engaging member. More closely spacedsupport members may provide significantly increased reinforcement ofground engaging members and may be suitable for providing traction onrelatively hard surfaces. Conversely, more spaced apart support membersmay provide a less significant amount of reinforcement and may be moresuitable for relatively softer surfaces. In addition, in someembodiments, the spacing about a ground engaging member may besubstantially the same between all support members abutting that groundengaging member. In other embodiments, the spacing between such supportmembers may be uneven.

In some embodiments, spacing between three or more support membersabutting a common ground engaging member may be substantially the samebetween each support member. For example, referring again to FIG. 10,the spacing between elongate support members 1030 may be substantiallythe same. For example, as shown in FIG. 10, first elongate supportmember 1035 and second elongate support member 1040 may be separated bya first angle 1070. Second elongate support member 1040 and thirdelongate support member 1045 may be separated by a second angle 1075. Inaddition, third elongate support member 1045 and first elongate supportmember 1035 may be separated by a third angle 1080. As illustrated inFIG. 10, the spaces between elongate support members 1030 may be devoidof additional support members. Since the spacing between elongatesupport members 1030 may be substantially the same, in such embodiments,first angle 1070, second angle 1075, and third angle 1080 may each beapproximately 120 degrees.

Referring again to FIG. 11, in some embodiments, three or more supportmembers may be unevenly spaced about a common ground engaging member towhich the support members abut. As shown in FIG. 11, elongate supportmembers 1130 may be unevenly spaced about ground engaging member 1110.In some embodiments, first angle 1170 and second angle 1175 may besubstantially different than third angle 1180, as discussed above. Also,as illustrated in FIG. 11, the spaces between elongate support members1130 may be devoid of additional support members. In addition, each ofelongate support members 1130 may be independent of other groundengaging members included on sole component 1100.

It should be noted that, although FIG. 10 depicts evenly spaced supportmembers about a round ground engaging member and FIG. 11 depictsunevenly spaced support members about an elongate ground engagingmember, spacing is not necessarily tied to the shape of the groundengaging member. Therefore, embodiments are envisaged wherein evenlyspaced support members are disposed about an elongate ground engagingmember, and likewise, embodiments are conceived wherein unevenly spacedsupport members are disposed about a round ground engaging member.

Sizing of Support Members

As discussed above, the sizing of a support member may have asignificant effect on the amount of reinforcement, ground penetrationand extraction, and traction provided by the support member.Accordingly, the sizing of each support member may be selected accordingto considerations discussed above in order to achieve desiredperformance characteristics.

In some cases variations in support member shape may influence the sizeof the support member. FIG. 6A illustrates how differences in shape maydictate changes in size. For example, as shown in FIG. 6A, each ofsupport members 630 may have substantially the same height. That is, H1,H2, and H3 may be substantially the same. However, by varying the lengthof support members 630 about ground engaging member 910, support member630 may be given a different shape. Since the height is the same acrossall three support members 630, changing the length of the support memberresults in a difference in overall size of the support member (and theamount of material used to form the support member). That is, in thiscase, the triangular surface area of vertical surfaces 640 respectivelyincreases and decreases with increases and decreases in support memberlength. Therefore, not only do the changes in shape influence thereinforcement, ground penetration, and traction, but also the changes inshape can result in changes in support member size, which can alsoinfluence these characteristics. In other embodiments, the changes inshape may be substantially more complex, and so too can the resultingchanges in size.

It should also be noted that even support members having substantiallythe same dimensions (e.g., length, width, and height), may have minordifferences in overall size due to irregularities in the surfaces of thecomponents to which the support members abut. For example, contours ofthe bottom surface of the baseplate, as well as the flaring of theground engaging members near the junction between the ground engagingmembers and the baseplate may dictate small variations in the overallsizes of support members abutting these components. In addition, theangle at which a support member adjoins, for example, an elongate groundengaging member may influence the size of the support member. Forexample, if an elongate support member adjoins an elongate groundengaging member at a non-perpendicular angle, one side of the supportmember may be longer than the other. These subtle variations in shapeand size may or may not have a significant effect on the resultingreinforcement, ground penetration and extraction, and traction providedby the support members.

As discussed above, in some embodiments, it may be advantageous, forvarious reasons, to have the configuration of each support member abouta common ground engaging member to be substantially the same. In otherembodiments, it may be beneficial for the configurations to differ. Asdiscussed above, it may be advantageous to have the orientation ofsupporting members to be consistent or inconsistent about a commonground engaging member, depending on the desired performancecharacteristics. The orientation of support members may be selectedindependently of the size and shape of the support members, although allof these parameters may have collective effects on the reinforcement,ground penetration and extraction, and traction. Similarly, the sizingof support members may be selected independently of shape andorientation. For example, the sizing of support members about a commonground engaging member may be consistent, despite any inconsistency inthe orientation of the support members. In some embodiments, the supportmembers about a common ground member may be inconsistently oriented, forexample, the support members may be unevenly spaced about the groundengaging member and/or some of the support members may be radiallyoriented and others may be non-radial. In such embodiments, the sizing(and/or shape) of the support members may be consistent.

FIG. 9 illustrates an exemplary embodiment, wherein support members 930having the same size are disposed about ground engaging member 910.

Regarding the dimensions of support members 930, the heights of supportmembers 930 may be substantially the same. For example, as shown in FIG.9, first elongate support member 935 may have a first height 982, secondelongate support member 940 may have a second height 984, and thirdelongate support member 945 may have a third height 986, wherein firstheight 982, second height 984, and third height 986 may be substantiallythe same.

As discussed above, it may be advantageous to have the orientations andspacing of supporting members to be consistent or inconsistent about acommon ground engaging member in order to provide certain desiredperformance characteristics. The size and shape of support members maybe selected independently of the orientation and/or spacing of thesupport members.

Referring again to FIG. 10, support members 1030 may have even spacingabout ground engaging member 1010, and may also have consistentorientations, wherein each of support members 1030 may be oriented in asubstantially radial direction. Nevertheless, even as the spacing andorientation of support members 1030 may be substantially consistent, andthe shape of ground engaging member 1010 may be substantially regular(in this case round), the sizing of support members 1030 may besubstantially uneven. As shown in FIG. 10, first elongate support member1035 may have a first length 1082. In addition, second elongate supportmember 1040 may have a second length 1084, and third elongate supportmember 1045 may have a third length 1086. As shown in FIG. 10, firstlength 1082 of first elongate support member 1035 may be substantiallythe same as second length 1084 of second elongate support member 1040.However, as also shown in FIG. 9, third length 1086 may be substantiallydifferent (in this case longer) than first length 1082 and/or secondlength 1084.

With further regard to the size of support members, the thickness may beone of several significant factors that determine the performancecharacteristics of an elongate support member. In some embodiments,desired reinforcement, ground penetration and extraction, as well astraction may be provided by elongate support members having a width(thickness) in a horizontal direction that is smaller than the width ofthe ground engaging member to which it abuts. In some embodiments, thewidth of the support member may also be smaller than the width of anelongate ground engaging member to which it abuts.

Referring again to FIG. 11, one or more of support members 1130 may havea horizontal width that is narrower than ground engaging member 1110. Asshown in FIG. 11, ground engaging member 1110 may be substantiallyelongate along ground engaging member axis 1155 oriented in a firsthorizontal direction. Ground engaging member 1110 may have a groundengaging member width 1180 in a second horizontal direction that issubstantially perpendicular to the first horizontal direction. As shownin FIG. 11, first elongate support member 1135 may have a support memberwidth 1182. As further shown in FIG. 11, support member width 1182 maybe smaller than ground engaging member width 1180.

It is noted that, although a larger base width 1184 of ground engagingmember 1110 is illustrated in FIG. 11 (and in other bottom views, suchas FIGS. 9 and 10), base width 1184 corresponds with a flared aspect atthe top of ground engaging member 1110. Consequently, the larger basewidth 1184 may be substantially limited to the uppermost portion ofground engaging member 1110, and thus, substantially the entire heightof ground engaging member 1110 may have a thickness that approximatesground engaging member width 1180. Other configurations are alsopossible.

With further regard to the size of support members, the height ofsupport members is one dimension that is a factor in the ultimate sizeof support members. In some embodiments the height of support membersmay be similar or the same as the height of the ground engaging memberto which the support members are abutted (a configuration not shown inthe accompanying figures). In other embodiments, the height of supportmembers may be shorter than the height of the ground engaging member towhich the support members are abutted. For example, in some embodiments,support members may extend downward from the bottom surface of theground engaging sole component less distance than the first groundengaging member extends downward from the bottom surface of the groundengaging sole component. Such a configuration may facilitate groundpenetration and/or ground extraction of the ground engaging members dueto the periphery of the ground engaging members being unencumbered byadditional elements at the tip portions of the ground engaging members.The difference in the heights of the support members and the groundengaging members may be selected in order to achieve desiredperformance, such as desired levels of reinforcement, ground penetrationand extraction, and/or traction.

FIG. 13 is a bottom, perspective view of a heel region of an exemplaryground engaging sole component 1300. Sole component 1300 may include abaseplate 1302 having a bottom surface 1305. Sole component 1300 mayalso include one or more ground engaging members 1310. For example, solecomponent 1300 may include a first ground engaging member 1315 and asecond ground engaging member 1320. Sole component 1300 may furtherinclude one or more elongate support members 1330.

As shown in FIG. 13, ground engaging members 1330 may have a groundengaging member height 1335. That is, ground engaging member 1330 mayextend downward from bottom surface 1305 of baseplate 1302 a distanceequivalent to ground engaging member height 1335. In addition supportmembers 1330 may have a support member height 1340. That is, supportmembers 1330 may extend downward from bottom surface 1305 of baseplate1302 a distance equivalent to support member height 1340. In someembodiments, as shown in FIG. 13, support members 1330 may extenddownward from bottom surface 1305 of baseplate 1302 less distance thanground engaging members 1310 extend downward from bottom surface 1305 ofbaseplate 1302. That is, support member height 1340 may be shorter thanground engaging member height 1335. In some embodiments, at least one ofsupport members 1330 may extend more than half of the distance thatground engaging members 1310 extend downward from bottom surface 1305 ofbaseplate 1302, as shown in FIG. 13. In other embodiments, not shown,support members 1330 may extend half the distance or less than half thedistance that ground engaging members 1310 extend from bottom surface1305 of baseplate 1302.

Although the embodiments illustrated in the accompanying figures showsupport members about a common ground engaging member to havesubstantially the same heights, it is envisaged that certain embodimentsmay implement arrangements of support members wherein the heights ofsupport members about a common ground engaging member are inconsistent.

Materials of Support Members

Suitable materials for forming ground engaging sole components aredescribed above. As noted above, different components of the solecomponents may be formed of the same or different materials. In someembodiments, at least one of a plurality of support members abutting acommon ground engaging member may be formed of the same material as atleast a portion of the ground engaging member. This may facilitate themolding process of the ground engaging sole components. In otherembodiments, the support members may be formed of a different materialthan the ground engaging member to which the support members areabutted. For example, it may be desirable to provide a support memberthat is substantially more rigid than the ground engaging member. Withsuch a configuration, rigidity can be selectively provided to differentaspects of the ground engaging member, in similar ways that thepositioning, orientation, shape, and size of support members mayselectively alter the performance characteristics of ground engagingmembers.

Further, in some embodiments, different portions of the same groundengaging member may be formed of different materials. For example, aground engaging member may be formed of one material in portions wheresupport members abut the ground engaging member, and may be formed of adifferent material in portions where support members do not abut theground engaging member. In some embodiments, upper portions of groundengaging members, where support members are abutted, may be formed of afirst material, whereas lower portions of ground engaging members, belowthe downward-most portions of support members, may be formed of adifferent material. The selection of these materials may be based on theperformance characteristics of the materials in terms of providingstrength, rigidity, ground penetration and extraction, and traction. Insome embodiments the lower portions (e.g., tip portions) of groundengaging members may be formed of relatively softer materials (e.g.,hard rubber) than upper portions of the ground engaging members. Thismay improve traction on various surfaces, and may also resist wear onnon-playing surfaces (e.g., pavement) before and after participating inthe activities for which the footwear is suited.

With further regard to FIG. 13, ground engaging members 1310 areillustrated as being divided vertically by a separator line 1345, whichserves to delineate a ground engaging member upper portion 1350 and aground engaging member lower portion 1355. In some embodiments, one ormore of support members 1330 may be formed of the same material as atleast a portion of ground engaging members 1310. For example, in someembodiments, support members 1330 may be molded simultaneously withupper portions 1350 of ground engaging members 1310, which are theportions of ground engaging members 1310 to which support members 1330are abutted. In other embodiments, ground engaging members 1310 andsupport members 1330 may be formed of different materials.

Further, whether the two components are formed of the same material ornot, the components may be joined after initial formation of one or bothof the components. For example, in some embodiments, portions of solecomponent 1300, including baseplate 1302 and ground engaging members1310, may be formed by a first molding process. Then, in an assemblyprocess, support members 1310 may be welded to the preformed solecomponent 1300. Alternatively, in a second molding process, supportmembers 1330 may be molded to the preformed portions of sole component1300.

In some embodiments the tip portions of ground engaging members 1310that extend below the downward-most portion of support members 1330 maybe formed of a different material than the rest of ground engagingmembers 1310. For example, in some embodiments, lower portions 1355 ofground engaging members 1310 may be formed of a softer material thanupper portions 1350 of ground engaging members 1310.

It is also noted that lower portions 1355 of ground engaging members1310 may be replaceable. For example, lower portions 1355 may beremovable cleat studs, which may be removably fastened to upper portions1350 using any suitable fastening system, such as threads (such groundengaging members may sometimes be referred to as “screw-ins”). Such aconfiguration may enable a user to replace lower portions 1355, forexample, when lower portions 1355 become worn, and/or in order tosubstitute a differently configured lower portion 1355. In some casesreplacement lower portions 1355 may have different shapes, sizes, and/ormay be formed of different materials.

Relationships with Other Ground Engaging Members

Support members may provide improved reinforcement, ground penetrationand extraction, and/or traction by virtue of the relationship betweensupport members abutting one ground engaging member and the supportmembers abutting a ground engaging member (and/or with the other groundengaging member itself) in the same arrangement. For example, in somecases, a common support member may be abutted to more than one groundengaging member. In some embodiments, for example, a support member maybridge between two ground engaging members to thereby form a braced, andthus reinforced, traction system. In some cases, the combination of thetwo ground engaging members and the bridging support member may providestrength, rigidity and/or traction in greater amounts than theindividual components would separately.

As shown in FIG. 13, elongate support member 1330 may extendhorizontally between first ground engaging member 1315 and second groundengaging member 1320 abutting both. Further, support member 1330 mayhave a downward facing surface 1365. In some embodiments, downwardfacing surface 1365 may include multiple facets. For example, as shownin FIG. 13, downward facing surface 1365 may include three facets. Afirst facet 1365 may be angled upward and away from first groundengaging member 1315 in the direction of second ground engaging member1320. In addition, a second facet 1370 may be angled upward and awayfrom second ground engaging member 1320 in the direction of first groundengaging member 1315. Further, a third facet 1375 may be disposedbetween first facet 1365 and second facet 1370. In addition, as shown inFIG. 13, third facet 1375 may be substantially horizontal.

In some embodiments, sole component 1300 may further includes second andthird elongate support members 1380, 1382, extending substantiallydownward from bottom surface 1305 of baseplate 1302, abutting firstground engaging member 1315, and extending horizontally from firstground engaging member 1315. In addition, sole component 1300 may alsoinclude fourth and fifth elongate support members 1384, 1386 extendingsubstantially downward from bottom surface 1305 of baseplate 1302,abutting second ground engaging member 1320, and extending horizontallyfrom second ground engaging member 1320. As shown in FIG. 13, first,second, third, and fourth support members 1380, 1382, 1384, and 1386 maybe arranged to form an H configuration.

Bridging support member configurations may be utilized at any suitableregion of the foot. One exemplary location where the added rigidity of abridging support member may be advantageous may include the heel region,as shown in FIG. 13. The heel region is often desired to be a relativelystiff area of an article of footwear. Further, as discussed above, theheel region is often raised to a certain extent and, therefore, groundengaging members in a heel region may be longer than in a forefootregion. Accordingly, it may be beneficial to reinforce longer groundengaging members in a heel region with a bridging support member.

FIG. 14 is a bottom, perspective view of a heel region having analternative bridging support member embodiment. As illustrated in FIG.14, an exemplary ground engaging sole component 1400 may include abaseplate 1402 having a bottom surface 1405. Sole component 1400 mayalso include one or more ground engaging members 1410. Sole component1400 may further include one or more elongate support members 1430.

In some embodiments, support members 1430 may be arranged to form an Xconfiguration between ground engaging members 1410. Sole component 1400may include a front left ground engaging member 1435, a rear left groundengaging member 1440, a rear right ground engaging member 1445, and afront right ground engaging member 1450. Each of these ground engagingmembers may have an elongate support member abutted to it and extendinghorizontally inward toward a lateral midline of sole component 1400. Forexample, a front left elongate support member 1455 may extend from frontleft ground engaging member 1435, a rear left elongate support member1460 may extend from rear left ground engaging member 1440, a rear rightelongate support member 1465 may extend from rear right ground engagingmember 1445, and a front right elongate support member 1470 may extendfrom front right ground engaging member 1450. Support members 1430 mayextend inward and intersect at a central portion 1475, thus forming an Xconfiguration.

In some cases, it may be beneficial to dispose support members such thatthey are independent of any other ground engaging members. Further, itmay be advantageous to orient support members such that the direction inwhich they extend from the ground engaging member to which they areabutted is not aligned with any other ground engaging members. Bymaintaining independence between different ground engaging members (andindependence between the support members abutting one ground engagingmember and the support members abutting other ground engaging members),spacing may be provided that may improve traction, for example, onrelatively softer surfaces. Also keeping the components separate mayprevent an excess of rigidity from being established by virtue oflinking ground engaging members and the associated structures (forexample, the support members), for example, in areas of the solecomponent where flexibility may be desired.

FIG. 15 is a bottom view of an exemplary ground engaging sole component1500. Sole component 1500 may include a baseplate 1502 having a bottomsurface 1505, and one or more ground engaging members 1510 extendingfrom bottom surface 1505 of baseplate 1502. Sole component 1500 may alsoinclude one or more elongate support members 1530. In some embodiments,sole component 1500 may include a first forefoot ground engaging member1532, a second forefoot ground engaging member 1534, a third forefootground engaging member 1536, a fourth forefoot ground engaging member1538, a first heel ground engaging member 1540, and a second heel groundengaging member 1542.

Support members 1530 may include, abutting first forefoot groundengaging member 1532, a first elongate support 1545, a second elongatesupport member 1550, and a third elongate support member 1555. As shownin FIG. 15, first elongate support 1545 may extend horizontally fromfirst forefoot ground engaging member 1532 in a first directionindicated by a first axis 1560. Second elongate support member 1550 mayextend horizontally from first forefoot ground engaging member 1532 in asecond direction indicated by a second axis 1565. Third elongate supportmember 1555 may extend horizontally from first forefoot ground engagingmember 1532 in a third direction indicated by a third axis 1570. In someembodiments, first axis 1560, second axis 1565, and/or third axis 1570may be not aligned with any of ground engaging members 1510 on solecomponent 1500, as shown in FIG. 15. As further shown in FIG. 15, insome embodiments all of the support members (1530) abutted to theforefoot ground engaging members (1532, 1534, 1536, and 1538) may extendin directions that are not in alignment with any other forefoot groundengaging members 1532, 1534, 1536, and 1538. Axes are omitted from theother forefoot ground engaging members besides first forefoot groundengaging member 1532 for purposes of maintaining clarity ofillustration. However, it will be understood, that as depicted in FIG.15, the support members abutting second, third, and fourth forefootground engaging members 1534, 1536, and 1538 extend in substantialnon-alignment with any of the other forefoot ground engaging membersextending from baseplate 1502.

In some embodiments, the baseplate may have gaps or cutouts in the platein order to allow different regions of the baseplate to flex in certainways. It may be desirable, however, to maintain strength and rigidity inthe baseplate portions that are adjacent to the gaps. In someembodiments, elongate support members may be oriented in such a mannerthat not only do the support members reinforce ground engaging membersto which the support members are abutted, but they may also reinforceregions of the ground engaging sole component baseplate adjacent to agap in the baseplate.

As shown in FIG. 15, sole component 1500 may have a first gap 1575adjacent to a protruding portion 1580. In some embodiments, secondelongate support member 1550, abutting first forefoot ground engagingmember 1532, may extend into first protruding portion 1580 in order toprovide reinforcement (strength and/or rigidity). In addition, solecomponent 1500 may also include a second gap 1582 adjacent to a secondprotruding portion 1584. Sole component 1500 may also include a fourthelongate support member 1586, abutting fourth forefoot ground engagingmember 1536. As shown in FIG. 15, fourth elongate support member 1586may extend into second protruding portion 1584 to provide reinforcement.Such baseplate reinforcement may be provided by elongate support membersin any portions of the baseplate, including portions that are near gapsin the baseplate, as well as portions that are relatively distanced fromgaps.

It may also be advantageous to implement elongate support members toprovide reinforcement to portions of ground engaging members proximateto areas of ground engaging members from which material is absent. Forexample, it may be beneficial to form a ground engaging member, in someembodiments, with a hole in a central portion in order to reduce weight.In such embodiments, it may be desirable to provide the baseplate withan elongate support member abutting the ground engaging member inalignment with the hole. This may reinforce the ground engaging memberin an area where the amount of material forming the ground engagingmember has been reduced. While including such a support member may addweight back into the sole component, the weight may be added in a mannerthat provides reinforcement in a directional manner. In addition, bymoving the material to a support member, the material may be used toalso provide additional traction.

Referring again to FIGS. 4A and 4B, ground engaging member 410 mayinclude hole 415 passing substantially horizontally through groundengaging member 410. In addition, as shown in FIGS. 4A and 4B, elongatesupport member 430 may include an aligned support member 455 abuttingground engaging member 410 in substantial alignment with hole 415.

In some embodiments, it may be advantageous to have one or more forefootsupport members that extend in a relatively lateral orientation. Thismay provide desired longitudinal traction, and reinforcement of thebaseplate in a central portion between lateral and medial groundengaging members. In some embodiments, it may be beneficial to extendthe support members at slight angles relative to the lateral-medialdirection. For example, in some embodiments generally laterally orientedsupport members in a forefoot region of the baseplate may extend atrelatively shallow angles. Laterally oriented support members extendingfrom first and second forward ground engaging members may intersect at apoint forward of a line connecting first and second rearward groundengaging members. Alternatively or additionally, laterally orientedsupport members extending from first and second rearward ground engagingmembers may intersect at a point rearward of a line intersecting firstand second forward ground engaging members.

FIG. 16 is a bottom view of the forefoot region of the ground engagingsole component configuration shown in FIG. 15. As shown in FIG. 16,second ground engaging member 1534 may include a first laterallyoriented support member 1588 abutting second ground engaging member 1534and extending laterally in a direction toward a lateral midline 1589 ofbaseplate 1502, wherein the direction is illustrated by a first lateraldirection axis 1590. In addition, third ground engaging member 1536 mayinclude a second laterally oriented support member 1592 abutting thirdground engaging member 1536 and extending laterally in a directiontoward lateral midline 1589 of baseplate 1502. First lateral directionaxis 1590 and second lateral direction axis 1594 may intersect at anintersection point 1596. In some embodiments, intersection point 1596may be forward of a line connecting first forefoot ground engagingmember 1532 and fourth forefoot ground engaging member 1538. Thedistance between intersection point 1596 and the forward-most portion(indicated by line 1599) of the line 1597 connecting first forefootground engaging member 1532 and fourth forefoot ground engaging member1538 is illustrated as longitudinal distance 1598.

FIG. 17 is a bottom view of the forefoot region of an exemplary groundengaging sole component. As shown in FIG. 17, sole component 200 mayinclude a first rearward ground engaging member 250, a second rearwardground engaging member 255, a first forward ground engaging member 260,and a second forward ground engaging member 265. In addition, solecomponent 200 may also include a first laterally oriented support member270 abutting first rearward ground engaging member 250 and extendinglaterally in a direction toward a lateral midline 272 of baseplate 202,wherein the direction is illustrated by a first lateral direction axis274. In addition, sole component 200 may include a second laterallyoriented support member 276 abutting second rearward ground engagingmember 255 and extending laterally in a direction toward lateral midline272 of baseplate 202, wherein the direction is illustrated by a secondlateral direction axis 278. First lateral direction axis 274 and secondlateral direction axis 278 may intersect at an intersection point 280.In some embodiments, intersection point 280 may be rearward of a line282 connecting first forward ground engaging member 260 and secondforward ground engaging member 265. The distance between intersectionpoint 280 and the rearward-most portion (indicated by line 290) of line282 connecting first forward ground engaging member 260 and secondforward ground engaging member 265 is illustrated as longitudinaldistance 284.

For purposes of explanation, the orientation of support membersextending from forward ground engaging members is discussed inconjunction with FIG. 16, and the orientation of support membersextending from rearward ground engaging members is discussed separatelyin conjunction with FIG. 17. However, it should be noted that, in theembodiment shown in FIG. 16, the rearward support members may beoriented as shown in FIG. 17, and are depicted as such in FIG. 16. Thedimensioning illustrating this feature has been omitted from FIG. 16 inorder to maintain the clarity of the drawing. Similarly, in theembodiment shown in FIG. 17, the forward support members may be orientedas shown in FIG. 16, and are depicted as such in FIG. 17. Again, thedimensioning illustrating this feature has been omitted from FIG. 17 inorder to maintain the clarity of the drawing.

In some embodiments, it may be advantageous to include one or moresecondary traction features at various portions of the sole component.In some embodiments, it may be beneficial to provide such secondarytraction features proximate to one or more ground engaging members. Insome cases, secondary traction features, such as a textured tractionsurface may be disposed between elongate support elements abutting andextending from a ground engaging member.

FIG. 18 is a perspective bottom view of the sole component embodimentshown in FIGS. 15 and 16. As shown in FIG. 18, sole component 1500 mayinclude first laterally oriented support member 1588, a forward-orientedelongate support member 1512, and an additional elongate support member1514 abutting and extend from second forefoot ground engaging member1534. In some embodiments, as shown in FIG. 18, sole component 1500 mayinclude a textured element 1516, which may be disposed, at least inpart, between support members 1588 and 1512, and/or between supportmembers 1512 and 1514.

Textured element 1516 may include textured traction surface including aplurality of peaked ground engaging members 1518. (See FIG. 1.) Peakedground engaging members 1518 may have a height that is substantiallyless than ground engaging members 1510. In some embodiments, peakedground engaging members 1518 may have a height in the range of about1.0-5.0 mm. In some cases, the height of peaked ground engaging members1518 may be in the range of about 1.5-2.5 mm, for example approximately2.0 mm.

For purposes of this disclosure, the term “between,” as used in thecontext of the placement of textured elements between support members,refers to being either “linearly between” or “rotationally between”support members, as explained in the following paragraphs.

In some embodiments, textured element 1516 may be disposed, at least inpart, linearly between support members. As illustrated in FIG. 18, alinear boundary between support members 1588 and 1512 is illustrated byline 1520. As illustrated in FIG. 18, at least a portion of texturedelement 1516 may be disposed within the linear boundary delineated byline 1520. Thus, at least a portion of textured element 1518 may bedisposed linearly between support members 1588 and 1512. That is, atleast one line can be drawn between support members 1588 and 1512 thatcrosses textured element 1518.

In some embodiments, textured element 1516 may be disposed rotationallybetween support members. In some cases, a textured element may bedisposed rotationally between support members but may not be linearlybetween the support members. As shown in FIG. 18, a linear boundarybetween support members 1512 and 1514 is illustrated as line 1522. Asfurther shown in FIG. 18, in some embodiments, no portion of texturedelement 1518 may fall within the boundary delineated by line 1522.However, a rotational boundary between support members 1512 and 1514 maybe indicated by rotational line 1524. As indicated in FIG. 18, at leasta portion of textured element 1518 may be disposed within the rotationalboundary delineated by rotational line 1524. Thus, at least a portion oftextured element 1518 may be disposed rotationally between supportmembers 1512 and 1514.

FIG. 19 illustrates an exemplary ground engaging sole component 1900.Several aspects of FIG. 19 are shown in other figures, for example,FIGS. 5, 7, 10, and 14. In addition, various features of sole component1900 are discussed above in conjunction with other embodiments.

FIG. 20 illustrates an exemplary ground engaging sole component 2000.Several aspects of FIG. 20 are shown in other figures, for example,FIGS. 3A, 3B, 4A, and 4B. In addition, many of the features of solecomponent 2000 are discussed above in conjunction with otherembodiments.

Although many possible combinations of features are shown in theaccompanying figures and discussed in this detailed description, manyother combinations of the disclosed features are possible. Therefore, itwill be understood that any of the features shown and/or discussed inthe present disclosure may be implemented together in any suitablecombination.

Observable Functionality

The shapes and orientations of support members disclosed herein, may benon-symmetrical, and/or irregular, and thus, may be indicative toobservers (for example, potential users) that the shapes andorientations are purposeful for more than mere aesthetics. The shape,placement, orientation, and/or size of support members may indicate tousers that the sole structure has certain performance characteristics.For example, placement of a support member abutting a ground engagingmember may indicate that the ground engaging member is reinforced.Further, the orientation of the support member may indicate thedirection in which the ground engaging member has been reinforced.

In some cases, an athlete who has experienced a broken cleat stud may beshopping for a shoe with stronger cleat studs. The athlete may, whenshopping for new shoes, find a shoe with a sole structure having a cleatstud with one or more abutting support members and assess that the cleatstud with abutting support members may be reinforced. While thequantitative degree to which the cleat stud is reinforced may not beevident from mere visual observation, the visually-observablequalitative characteristic of the cleat stud being reinforced mayprovide a basis upon which an athlete may select a particular shoe.

In addition, the location and orientation of the support member mayindicate that additional traction is provided in a direction generallyperpendicular to the support member. Accordingly, a potential userlooking for a shoe having ground engaging members with improved tractionin a particular location and/or direction may observe attributes of asole structure that provide the desired characteristics. For example, anathlete may find that lateral traction is less than desired in a regionof his current shoes that corresponds with the distal portion of thefirst phalanx. The athlete may, when shopping for a new shoe, observethat an available shoe has a cleat stud in this region that includes,abutting the cleat stud, one or more support members that are orientedlongitudinally. Accordingly, the athlete may be able to assess thatadditional lateral traction may be provided by the support members.While the quantitative amount of traction provided by the supportmembers may not be readily observed visually, the visually-observablequalitative characteristic of directional traction (specifically lateralin this case) may provide a basis upon which an athlete may select aparticular shoe.

Selection of shoes is discussed above as being associated with a shoepurchase. However, the factors considered above in conjunction with apurchase may also apply to choosing a shoe from an owner's collection touse for a particular event. For example, a user may find that additionallateral heel traction is beneficial when playing on soft, wet turf.Accordingly, when choosing a shoe for an event that is to be played onsoft, wet turf, the athlete may select, from his own shoe collection, ashoe having longitudinally oriented support members abutting heel cleatstuds.

While various embodiments of the invention have been described, thedescription is intended to be exemplary, rather than limiting and itwill be apparent to those of ordinary skill in the art that many moreembodiments and implementations are possible that are within the scopeof the invention. Accordingly, the invention is not to be restrictedexcept in light of the attached claims and their equivalents. Also,various modifications and changes may be made within the scope of theattached claims.
